Known by various names, Bullshit grinder, Do nothing machine, Time waster, this toy has been around for years. My Dad was making them in the 50s. When the crank is turned two small pieces of wood move back and forth, up and down but never touch each other.
A must have when confronted with lawyers, used car salesmen, fishermen, golfers, hunters, gamblers, and various other liars.
Base measures 3 ½ x 3 ½ x 15/16 inhes.
